UNITED STATES Be it known thatI, HOWARD RANDALL, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have-invented new and useful Improvements in a Frictional Contact Window Guide, of which the following is a specification.

This invention is concerned with a yield ing guide, channel or run in which glass window panes may be retained or reciprocated and is particularly adapted to the doors and windows of closed motor cars, such as sedan automobiles and similar uses, and the form ofthe structure may be modified to adapt it to various other uses.

This invention has for one of itsobjects the provision of a channel device so formed of metallic and flexible covering'that the points of engagement with the glass will be and firm and yet the other parts of the device and particularly the base portion will be sufiiciently fiexbile to insure the device fitting properly within the channel or way, and that there will be a certain independence of movement of the base glass, such that the engagingportions will not interfere with the flexibility vof the other portions, and vice versa.

This invention has for another object the providing of engaging points with the glass that have a positive spring contact therewith and in providing a structure of the class described that ma be economically and expeditiously produce and applied.

These and other objects are attained by the means described herein, and disclosed in which:

FBICTIONAL CONTACT WINDOW GUIDE.

Original No. 1,530,895, dated March 24, 1925, Serial No. 721,641, filedJune 23, 1924. Application for 7 reissue filed. Kay 23, 1925. Seriall'o. 32,518.

ber, for which a flexible covering 11, hereafter called the non-metallic member, is pro vided. The core 12 is produced preferably desired spring characteristics, and is preferably bent backwardly and forwardly 1n the manner disclosed 'in Fig. 1 for providing a substantially flat rectangular wire mat. The wire 10 may be of any suitable cross section and the particular configuration of the various loopsdevelopedalongthe lateral edges of the wire mat may be varied and modified to meet various conditions, a main feature being that the base and sides constituting the body portion of the mat, when the mat orcore 12 is bent into channel shape, are of such reticulated or open character that, while the engaging edges or peripheries of mat 12 will hold the glass firmly with a spring action, the body portion of the mat or core will retain considerable flexibility and independence of movement without interfering with the holding capacity of those engaging edges.

The flexible covering 11, or non-metallic member, is preferably provided on its inner face with an adhesive so that when the wire mat 12 is placed upon the flexible covering 11, and the lateral ends 13 and 14: of the flexible material are bent over the wire mat, the adhesive will serveto bind the opposed portionsof the flexible material, where such sections contact through the openings 15 formed interiorl of the loops 16 developed along the lateral edges of the wire mat 12, and the open character of the base and sides of the metal member will enable the device to retain some of the plasticity of the covering which is desirable in this character of device.

In Fig. 2, the ends 13 and 14 are shown in dotted lines in their fixed positions relative to the underlyin position 17 of the covering material. T e structure, after fixation of the ends 13 and 14, is then bent to the desired form, for example to the channel forms shown in Figs. 3 and 5, whereupon the channel may be inserted in the run or way 18 that forms art of a vehicle door or the like, and in wliich the plate glass window 19 or the like is received. It will be readily evident that the flexible material 11 may be rein forced by capping the looped ends 12 of no the wire mat rior to the turning inward of the lateral e ges 13 and 14 of the flexible material 11. It will be readily evident that the flat structure disclosed in Fig. 2, after the ends 13 and 14 are aflixed, may be developed into various flexible forms other than the channel 20, wherefore I do not restrict my invention to the specific form into which such flat structure might be developed.

Although the invention as disclosed herein comprises spring wire having resilient qualities, it w ll be readily evident that under some circumstances such qualities might be undesirable, wherefore it is not intended to restrict the invention .to a structurewherein the wire is resilient or yielding. In applying the glass to the channel, it 1s apparent thatthe edges of the channel will be slightly unbent by the sliding action of the glass, a small part at a time.

Having described the invention, I claim as follows:

1. In a device of the character described the combination of a metallic member havin substantially continuous outer edges and a y portion of open character with a covering member of a flexible character, said members being bent to form a channel, and a glass member adapted to fit within said channel, the outer edges of said metallic member holdin said lass member by a sprin action w ile the ody portion of said metal ic member permits the the coverin able it to ad of use.

2. As a new article of manufacture a channel comprising a flexible covering, and

retention by member of its pliability to enapt itself to different conditions a resilient mat contained within the cover-- a continuous, sprin ing and comprising ternate directions, an

wire extending in a having its lateral edges disposed at angles to the intermediate portions thereof for providing the side walls of the channel.

3. A channel structure of U-shaped cross section comprising a resilient wire mat and a flexible covering for the mat, the mat comprising a serpentine wire looped along its lateral edges and having its lateral edges turned relative to the intermediate or base portion thereof, whereby the lateral portions of the wire mat form part of the arms of the channel and retain the lateral edges of the flexible covering at an angle to the center portion of the covering, the said lateral edges of the wire mat and flexible covering providing a way between them throug which way a sliding member may be moved, the arms of the channel yieldingly resisting movement of such sliding member.

4. A channel structure of U-shape cross section comfprising a resilient wire mat and a covering or the mat, the mat and covering being relatively fixed, the mat having its lateral edges turned at an angle and overhanging theintermediate portion or base of the structure for providing a way wider at its bottom than at its top and for yieldingly er resisting movement of a sliding mem through the way.-

5. In a channel device, the combination of a reticulated metal member with a nonmetallic member, the sides of the metal member being bent toform engaging spring arms having a channel formed by said arms, a slidable glass member fitting channel and en aged by said spring arms, thereticulated c aracter of the spring arms permitting the glass member to be inserted y s ringing back the arms, part ata time, ,unti the entire glass is inserted therein.
